Preservation:
PREVENTOL D 7 has a broad spectrum of activity, good water solubility and good biodegradability in the readyto- use concentration, making it a highly versatile preservative. The spectrum of activity of PREVENTOL D 7 covers bacteria, including formaldehyde-resistant types, mould fungi, yeasts and algae.
On account of its low viscosity, the preservative PREVENTOL D 7 can be processed either in undiluted form or diluted with water. The temperature should preferably not exceed 40°C.
PREVENTOL D 7 does not usually cause undesirable discoloration or other side effects. PREVENTOL D 7 is suitable for preserving products containing protein (e.g. casein). In view of the wide range of possible applications in practice, it is generally advisable to carry out preliminary trials to check the compatibility and determine the optimum concentration.
